Abstract: A moving robot has a body and at least one wheel for moving the main body. The moving robot has a transceiver to communicate with a plurality of location information transmitters located within an area. The moving robot also has a memory storing coordinate information regarding positions of the location information transmitters. Further, the moving robot has a controller that sets a virtual boundary based on location information determined using signals transmitted by the location information transmitters. The controller controls the wheel so that the main body is prevented from traveling outside the virtual boundary. The controller sets a reference location information transmitter and corrects the stored coordinate information by correcting height errors based on height differences between the reference location information transmitter and the other location information transmitters. The controller also corrects a current position of the main body based on the corrected stored coordinate information.

Abstract: Apparatus and associated methods relate to passive ranging of objects by using relative positional relation of the object to a coded aperture ranged object. A first range to a first object is determined via a coded-aperture ranging system based on a point spread function optimization of an image of the first object. The terrain surface between the first object and a second object is mapped via a 3D polarimetry system. A second range to the second object is then calculated via a range calculator based on the first range and the terrain surface between the first object and the second object.

Abstract: A method and an apparatus for generating positional sensor data of a coordinate measuring device are provided. A sensor generates sensor data points and a trigger signal with a trigger frequency. A sensor data record is generated which includes the sensor data points and a sensor data time. The trigger signal is transmitted to a device for determining a sensor position, a position data record is determined upon or after the reception of the trigger signal, the position data record includes at least one position data point and one position data time, an assignment of position data points to sensor data points is determined depending on the sensor data time and the position data time, and a positional sensor data record is generated which includes at least one sensor data point and a position data point assigned to this sensor data point.

Abstract: A surveying device is operated to measure a surface profile of a terrain of a worksite and generate surface profile data. Machine operational data is stored and associated with at least one gradient characteristic. A processing unit is operated to process the surface profile data to identify an area of the terrain and a gradient characteristic of the area and retrieve machine operational data associated with the gradient characteristic from the database and associate the machine operational data with the area. The work machine is operated in the area based upon the machine operational data.

Abstract: A multi-node data synchronous acquisition system and a method for real-time monitoring of underwater surface deformation. The system includes at least four sensor arrays, where each of the sensor array consists of a plurality of ribbon-like rigid substrates connected by movable joints. On each section of rigid substrate, three sensor units are respectively connected to a slave station data acquisition unit through cables. The slave station data acquisition unit is connected with a central controller through a cable. The central controller includes a compressive cabin outside and an embedded controller and a power supply inside. Each slave station data acquisition unit acquires data from an MEMS attitude sensor and then transmits it to the embedded controller. The present invention may realize synchronous acquisition of underwater or even underwater multi-node data, implement three-dimensional surface reconstruction, and may be used for improving the ocean observation capability.

Abstract: The disclosed subject matter relates to a laser scanner for scanning a ground from a seaborne or airborne vehicle, comprising a scanning unit for emitting a fan-shaped scan pattern made of laser beams fanned out about a scan axis and for receiving the laser beams reflected off the ground and an evaluation unit connected to the scanning unit for evaluating the laser beams that are received. The laser scanner is characterized by a measuring unit that is designed to measure the height of the vehicle above ground, and an actuation device that can be anchored to the vehicle and that is connected to the measuring unit. The actuation device is designed to rotate the fan-shaped scan pattern of the scanning unit with respect to the vehicle about a first actuation axis that is different from the scan axis, depending on the measured height above the ground.
